TECHNICAL FIELD

This patent disclosure relates, generally, to cleaning devices and systems and methods for monitoring the cleaning conditions of an interior environment of a facility and, more particularly, to such systems, methods, and cleaning devices having features and techniques for improving the ability to monitor the cleaning practices within a facility.

BACKGROUND

According to the Centers for Disease Control and Prevention (CDC), in 2015, costs for slip-and-fall accidents to Medicare alone totaled over $31 billion. This total does not include legal or non-Medicare related costs. The total expense resulting from slip-and-fall injuries in the United States is estimated to be approximately $100 million per day. According to the CDC, in 2008 more than 8.5 million Americans sustained injuries from an unintentional slip or fall—the leading cause of all nonfatal injuries treated in U.S. hospital emergency rooms. Common causes of slip-and-fall accidents include improper maintenance of walking and common areas, lack of cleanliness on floors leading to slippery surfaces when wet, and failure to clean floors after water or food spillage.

Slip and fall injuries are frequently associated with wet floors. Customers typically encounter such wet floors in the restroom of a facility, and employees frequently encounter such wet surfaces in a work area, such as a kitchen of a restaurant, for example. These injuries can result in numerous general liability and/or workers compensation claims.

Conventional techniques for evaluating floor conditions are complicated and expensive and are prone to human error. The cost and the effort involved in evaluating floor conditions makes the occurrence of such readings less frequent. This results in fewer safety readings being taken and a lack of alerts when dangerous floor conditions exist.

Most facilities depend on staff and janitorial contractors to self-report when they perform cleaning operations, typically via a hand-written log posted in an area designated for routine cleaning (e.g., a bathroom). This system is prone to human error and uncertain accuracy. It also requires manual effort to first enter the information and then to key it into an electronic format for management reporting. If a scheduled cleaning is not performed, it may be unlikely that a manager will discover such fact until much later, if at all.

There is a continued need in the art to provide additional solutions to help promote the cleanliness of facilities used by the public and to reduce the occurrence of slip-and-fall injuries. For example, there is a continued need for techniques for improving the ability to monitor the cleaning practices within a facility.

It will be appreciated that this background description has been created by the inventor to aid the reader, and is not to be taken as an indication that any of the indicated problems were themselves appreciated in the art. While the described principles can, in some respects and embodiments, alleviate the problems inherent in other systems, it will be appreciated that the scope of the protected innovation is defined by the attached claims, and not by the ability of any disclosed feature to solve any specific problem noted herein.

DETAILED DESCRIPTION

Embodiments of systems and methods for monitoring the cleaning conditions of a facility are described herein. Embodiments of a kit for reducing the occurrence of slipping upon a floor surface are described herein. Embodiments of a cleaning apparatus having a tracking device and suitable for use in systems and methods for monitoring the cleaning conditions of a facility are also described herein. Further and alternative aspects and features of the disclosed principles will be appreciated from the following detailed description and the accompanying drawings.

Embodiments of systems and methods for monitoring the cleaning conditions of a facility constructed according to principles of the present disclosure can be used to improve the cleanliness of a facility and to reduce the occurrence of slip-and-fall accidents caused by poor floor conditions. Embodiments of systems and methods for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to reduce the occurrence of slippery floor conditions at the facility by monitoring for the regular practice of cleaning operations according to a predetermined schedule and/or cleaning regime. In embodiments, a cleaning apparatus is equipped with a tracking device to monitor at least one of the location of the cleaning apparatus within the facility, the movement of the cleaning apparatus about the facility, and the dynamic coefficient of friction encountered by the cleaning head of the cleaning apparatus as it traverses over a flooring surface during a cleaning operation. The ability to substantially continuously monitor the use of the cleaning apparatus and record dynamic coefficient of friction (DCOF) data can help make the common use space of a facility safer where slippery floor conditions are less likely to exist.

Embodiments of systems and methods for monitoring the cleaning conditions of a facility following principles of the present disclosure can provide a slip reduction service (SRS) via a tracking device-enabled service that automatically reports floor conditions and cleaning operation parameters (such as, length and location of cleaning operation). Cleaning operation data records can be transmitted via a suitable Internet-of-things type connection, as one skilled in the art will appreciate, and stored in a cloud-based platform allowing for improved monitoring of cleaning conditions at a facility and better management of safety conditions, as a result. Continuous monitoring of cleaning operations can provide more accurate records and reduce the occurrence of slip-and-fall accidents.

Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to track the location within the facility that is being cleaned. Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to authenticate the identity of the operator performing the cleaning operation. Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to alert a manager when a specified cleaning operation has not been performed by a given time (or within a given frequency) and/or within a given area of the facility. In embodiments, the system can include at least one cleaning apparatus which can be any suitable cleaning implement, such as, a broom, a brush, a mop, a duster, a propelled sweeper, an automatic floor scrubber, etc.

Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to measure the floor condition through the dynamic coefficient of friction. Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to alert a manager when the floor conditions fall outside of a specified acceptable range (e.g., the measured dynamic coefficient of friction falls below a predetermined value for that particular area of the facility).

Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can include a central, cloud-based management system for analysis of the cleaning conditions of a given facility or over a number of different facilities within a designated region. Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can include a suitable data storage system for storing detailed cleaning operation data logs for a given facility to track trends and monitor the cleaning conditions of the facility against a historical trajectory. In embodiments, more and better quality information on floor conditions and cleaning operations can be collected by lowering the cost and complexity of obtaining the cleaning data relative to other techniques.

It can also alert the store management if the floor is unsafe (e.g., due to a low coefficient of friction reading) and needs attention. By obtaining cleaning condition data more frequently and/or on a substantially continuous basis can help a manager respond faster to floor condition issues that require attention, such as to mitigate a slipper floor condition.

Embodiments of a method for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to help reduce the chances of human error in obtaining cleaning data and the false reporting of cleaning operations. The cleaning data is captured and stored automatically without human intervention.

Embodiments of a system for monitoring the cleaning conditions of a facility following principles of the present disclosure can be used to monitor cleaning operations within a facility. This monitors the cleaning of the facility to track whether a specified cleaning operation was performed on time and in the right areas. In embodiments, the system is adapted to track the identity of the operator who performed a particular cleaning operation. The system captures details of when the cleaning was performed automatically. It also can issue an automatic alert to a manager (e.g., via an automatically-prepared text message) informing the manager when a scheduled cleaning operation was not performed.

The Figures show a number of different embodiments of a system for monitoring the cleaning conditions of a facility constructed according to principles of the present disclosure. The Figures also show embodiments of a cleaning apparatus constructed according to principles of the present disclosure. The system can reduce the manual effort expended to record and report the occurrence of cleaning operations and the floor conditions (e.g., via friction readings).

In embodiments, a system for monitoring the cleaning conditions of a facility constructed according to principles of the present disclosure can include a cleaning apparatus with a tracking device mounted thereto, a plurality of user identification devices to identify which one of a plurality of operators is performing a given cleaning operation, a plurality of beacons adapted to track the location of the cleaning apparatus throughout the facility, a computer environment adapted to collect cleaning data from the facility and to monitor the cleaning conditions of the facility based upon the cleaning data it receives therefrom, and a suitable bridge for communicating cleaning data from the facility to the computing environment. In embodiments, a system for monitoring the cleaning conditions of a facility constructed according to principles of the present disclosure can have different arrangements as one skilled in the art will appreciate in view of the present disclosure.

Referring to FIG. 1 , in one embodiment of a system 21 for monitoring a cleaning condition of a facility 22 constructed according to principles of the present disclosure, the system includes a cleaning apparatus 25, a tracking assembly 27, a non-transitory computer-readable medium 29, and a processor 30. The tracking assembly 27 is configured to monitor movement of the cleaning apparatus within the facility 22. The non-transitory computer-readable medium 29 bears a floor condition tracking program.

The tracking assembly 27 includes a first tracking unit 31 and a plurality of second tracking units 32. The first tracking unit 31 is associated with the cleaning apparatus 25. The second tracking units 32 are located in spaced relationship to each other within the facility. The first tracking unit 31 is configured to wirelessly emit a location signal. Each second tracking unit 32 is configured to interact with the first tracking unit 31 to detect when the cleaning apparatus 25 is within a detection area of the respective second tracking unit 32. The second tracking units 32 are configured to transmit location data concerning the cleaning apparatus 25.

In the illustrated embodiment, the first tracking unit 31 is mounted to the cleaning apparatus 25. In other embodiments, the first tracking unit 31 can also be in the form of a wearable communicator worn by the operator using the cleaning apparatus 25. The second tracking units 32 can be mounted in suitable locations about the facility, including either to walls or ceilings. The density of the second tracking units 32 distributed in the facility 22 can be adjusted according to intended cleaning operations desired to be monitored within the facility.

In embodiments, any suitable tracking units can be used. For example, in embodiments, suitable first and second tracking units 31, 32 can be used that are configured to communicate over one or more of Bluetooth, Wi-Fi, near field communication, and RFID arrangements. In one embodiment, the first tracking unit 31 is configured to generate a Bluetooth radio wave on a frequency between 2.402 GHz and 2.480 GHz, and the second tracking units 32 each comprises a Bluetooth beacon.

In embodiments, beacons 32 attached to the wall are used to track the location of the cleaning apparatus 25 within the facility. In embodiments, beacons 32 comprise any suitable device, such as a small, battery-operated unit that does not require any external wiring. In embodiments, the beacons 25 transmit their location via Bluetooth signals. A first tracking unit 31 attached to the cleaning apparatus 25 can be used to trigger the beacon 32 when the cleaning apparatus 25 is in the operating range of the beacon 32 to monitor the location of the cleaning apparatus within the facility 22.

Details on floor conditions and cleaning performed can be sent to a cloud-based platform. The beacons 32 can connect to a Wi-Fi network in the facility via a bridge 35 that can be tied into the electrical supply of the facility 22 (e.g., via a plug-and-receptacle connection or a hard-wired connection). The communication bridge 35 can be configured to receive location data from the beacons 32 and to transmit the location data to the processor 30. In embodiments, the bridge can be powered using the electrical supply found in the facility 22 (e.g., a standard wall receptacle).

The processor 30 is in operable arrangement with the second tracking units 32 to receive the location data and in operable arrangement with the non-transitory, computer-readable medium 29. The processor 30 is configured to execute the floor condition tracking program contained on the non-transitory computer-readable medium 29. The floor condition tracking program includes a tracking module configured to analyze the location data from the second tracking units 32 to determine whether a predetermined cleaning operation was performed within a specified time schedule.

In embodiments, the tracking module of the floor condition tracking program is configured, in response to determining a cleaning operation was not performed with the time schedule, to generate and send an electronic alert message 40 to at least one recipient to alert the recipient that the cleaning operation did not occur according to the time schedule. An example of such an alert 40 is shown in FIG. 1 . In embodiments, in the event that a threshold value is met, an alert message can also be sent to a manager (e.g., via a text message or an email message).

In embodiments, the tracking device 31 mounted to the cleaning apparatus 25 is adapted to interact with the beacons 32 in the facility 22 to monitor the location and movement of the cleaning apparatus 25 throughout the facility. In use, the cleaning apparatus 25 can be tracked by the system 21 to monitor that the operators are performing the designated cleaning operations in different areas of the facility 22 according to the designated cleaning schedule. For example, in embodiments, the tracking assembly 27 comprises an RFID tracking system, with tags that can be attached to a cleaning head of a cleaning apparatus in the form of a deck brush and submersible in water.

The system 21 is adapted to generate cleaning data that can be used to record when the cleaning apparatus 25 is in motion. This can be recorded in different areas of a restaurant or other facility 22.

Referring to FIG. 2 , information can be sent from the tracking device 31 of the cleaning apparatus 25 directly to the cloud 45 without any manual input. This also reduces the risk of human error and false reporting. The location is verified with beacons and the time and worker details are also automatically captured.

A mobile app for use on a portable device 47 (e.g., a smartphone) can be provided to allow an authorized user to access the cleaning data stored in the cloud 45. The cloud 45 can store a log of readings by time, operator, and location. The mobile app can be programmed to issue an alert if a slippery floor surface is detected or if a scheduled cleaning operation is not performed.

Referring to FIG. 3 , each operator can be issued a user identification device 43. The user identification device 43 can be configured to transmit an identification signal 47 configured to identify which one of a plurality of operators is associated with the user identification device 43.

The system 21 can also include an identification reader 45. In embodiments, the identification reader 45 can be associated with the cleaning apparatus 25. The identification reader 45 can be configured to interact with the user identification device 43 to receive the identification signal 47 from the user identification device 43 and to transmit the identification signal 47 to the processor 30. The tracking module of the floor condition tracking program can be configured to associate the location data received from the cleaning apparatus 25 to the operator associated with the identification signal 47 received from the identification reader 45.

In embodiments, each operator is provided with a small badge which communicates by RFID. Workers scan their badge over the sensor to identify themselves before performing the cleaning or taking a friction reading. Their worker ID is transmitted along with the readings they take (along with the location, time and sensor serial number).

RFID tags confirm the identity of the worker who is conducting the cleaning or taking the friction reading. In embodiments, the worker first scans their ID badge (with integrated RFID) on a small reader that is on the cleaning device to associate their identity with the use of the particular cleaning device. In embodiments, a location-driven inspection log can be generated at the facility using the worker ID device to provide confirmation of adherence to the predetermined cleaning schedule. In embodiments, any suitable device can be used as a worker ID device. For example, any suitable wearable device can be used that can be worn on wrists, vests, or in shoe soles.

Referring to FIG. 4 , in embodiments, the system 21 can be used to monitor for hazards and potential slip conditions. The operators can use the beacons to automatically document and time stamp their inspection of major areas by ‘tapping’ beacons to verify they actually checked the area for hazards. The beacons are distributed throughout the facility 22. The operator triggers a respective beacon in a designated location with the appropriate cleaning apparatus or other equipment, thereby time and date stamping the performed operation. The inspection log can be automatically updated to a secure cloud-based data vault. The log data can be retrieved for verification of operational standards and evidence of reasonable care, such as when defending a claim in a lawsuit.

FIG. 5 is a view of an embodiment of a graphical user interface 50 suitable for use with a floor condition tracking application constructed according to principles of the present disclosure. In the illustrated display 50, a series of proximity readings taken by a beacon with respect to the location tracking device 31 mounted to the cleaning apparatus 25 is displayed.

In the illustrated embodiment, dashboard details determined by a floor condition tracking application constructed according to principles of the present disclosure for a number of facilities distributed over a geographical region (e.g., over the United States of America) are displayed. The dashboard view shown in FIG. 8 can provide a snapshot of data for a series of facilities 22. In embodiments, each dot represents a predetermined geographical area containing multiple facilities or a given facility. Each area/facility can be double clicked to launch a separate window displaying detailed cleaning data for the selected area/facility. The aggregated cleaning data can be used to help determine information, such as, metrics indicating failure points, period-over-period trends, and forecasts for mean time before failure information, for example.

In embodiments, the cleaning apparatus can have any suitable configuration as one skilled in the art will appreciate. For example, in embodiments, the cleaning apparatus can be in the form of a deck brush 60 with a tracking device 61 mounted thereto under a protective layer 62 (see, e.g., FIGS. 9 and 10 ). In embodiments, the deck 64 can have bristles 65 attached thereto that are configured for performing a cleaning operation. In embodiments, the bristles 65 can be made from any suitable material, such as, any combination of ferrous wire, nonferrous wire, plastic, abrasive filaments, vegetable fibers, animal hair, or other materials known to those skilled in the art.

Referring to FIG. 11 , in embodiments, the cleaning apparatus can be in the form of a powered, walk-behind sweeper 70, such as those commercially-available from Tennant Co. of Minneapolis, Minn., or Global Industrial of Port Washington, N.Y., for example. In embodiments, the cleaning apparatus 70 includes a first tracking unit 71, a motion detector 72, and a communication device 73. The first tracking unit 71 can be configured to interact with the second tracking units 74 distributed throughout the facility in order to provide location data to the floor condition tracking program as previously described.

The sensor 72 can measure movement and be used to monitor how long the cleaning apparatus 70 is being used. In embodiments, a tracking device can be included that is configured to detect and capture movement, time and number of brush strokes (in embodiments in which the cleaning apparatus includes a brush head).

FIG. 12 is a view of an embodiment of a graphical user interface 81 suitable for use with a floor condition tracking application constructed according to principles of the present disclosure. In the illustrated embodiment, a series of movement readings taken by the accelerometer 72 mounted to the cleaning apparatus 70 is shown.

For example, in embodiments, the sensor is configured to measure the dynamic coefficient of friction of the floor surface over which the cleaning apparatus is moving. This dynamic coefficient of friction is a value that describe the ability of the surfaces to resist the sliding or slipping of an object across the surface. In general, the lower the coefficient of friction, the more slippery it can be considered. In embodiments, the system can be configured to obtain measurements form the tracking device that can be used to compute a dynamic coefficient of friction that correlates to one computed via the Dynamic Coefficient of Friction (DCOF) method in ANSI A137.1, the American National Standard Specifications for Ceramic Tile.

In embodiments, the cleaning apparatus can include a sensor in the form of a strain sensor. The strain sensor can be arranged with the cleaning apparatus such that the strain sensor is configured to measure a resistance encountered by the cleaning apparatus as the cleaning apparatus moves upon the surface. The strain sensor can be configured to measure the level of effort (tension) needed to move the cleaning device laterally over the floor. This measured strain can correspond to the coefficient of friction. The strain sensor can be configured to generate a strain signal indicative of the measured resistance. In embodiments, the strain sensor readings can be transmitted to a mobile app and also to a cloud based reporting service. In embodiments, the computing environment includes a floor condition tracking program that is adapted to determine a friction coefficient based upon the strain sensor readings. The floor condition tracking program can include a calculation code segment configured to determine a dynamic coefficient of friction encountered by the cleaning apparatus moving upon the surface based upon the strain signal received from the strain sensor.

In embodiments, the cleaning apparatus can be used to measure the surface friction coefficient to determine how slippery a floor surface is and to provide metrics that help facility managers determine whether their implemented cleaning procedures have improved the condition of the floor. An operator can use the slip meter to measure friction of the floor at pre-set locations and times. The floor condition data can be stored in a cloud-based storage. Data can be displayed on a dashboard for the time period selected. Measurement intervals can be varied in different embodiments (e.g., hourly, daily, weekly, and/or monthly). When a condition is detected that breach a threshold value, an automatic message can be generated and sent to selected managers for real time corrective action.

An example of a cleaning apparatus 80 with a sensor configured to determine the condition of the floor by assessing its coefficient of friction is shown in FIGS. 13 and 14 . Referring to FIG. 13 a scrubbing member of the cleaning apparatus 90 is shown that includes an on/off switch 91, a charging cord 92, a battery 93 (or other suitable power source), an accelerometer 94 to measure and detect movement and speed, a Bluetooth beacon 95 to determine the location of the cleaning apparatus 90 in the facility. The cleaning apparatus 90 includes a strain sensor 97 adapted to measure the resistance encountered by the cleaning apparatus 90 as it moves along the floor and a base plate 98 to protect the strain sensor 97. In embodiments, the base plate 98 can be made from any suitable material, such as a suitable acrylic, for example.

The strain sensor 97 is configured to be stretched as the cleaning apparatus 90 is moved over the floor via the sensor foot 99. The amount of stretch detected by the strain sensor is proportional to the friction that the cleaning apparatus 90 encounters on the floor. A floor condition tracking program constructed according to principles of the present disclosure can be used to determine a value for the dynamic coefficient of friction of the flooring surface over which the cleaning apparatus is travelling.

The strain sensor 97 is configured to measure a condition of a surface upon which the scrubbing member moves. The strain sensor 97 is configured to generate a condition signal indicative of the condition measured by the sensor. In the illustrated embodiment, the strain sensor 97 is configured to measure a resistance encountered by the scrubbing member as the scrubbing member moves along a surface being cleaned. The strain sensor 97 is configured to generate a strain signal indicative of the resistance.

The beacon 95 is in electrical communication with the strain sensor 97 to receive the condition signal. The beacon 95 is configured to transmit the condition signal to a remote receiver.

The dynamic coefficient of friction is measured as the cleaning apparatus 90 is rolled along the floor. The readings from the strain sensor 97 are reported in real-time to the cloud along with time, location in facility and the identity of the person who took the readings. This reduces the effort involved in taking readings, faulty reporting, and missed cleanings.

In embodiments, the self-contained tracking device can be in the form of a strain sensor attached to the cleaning device being used at the facility. The strain sensor can be adapted to continuously measure the dynamic coefficient of friction as the cleaning device moves over the floor. The strain sensor can be disposed within a housing to help enhance the durability of the sensor.

In embodiments, the cleaning apparatus is fitted with a sensor (e.g., a strain sensor) that produces measurements which can be correlated to the dynamic coefficient of friction on the floor's surface. It captures details of the worker performing the measurement as well as the location within the facility (from beacons) where the reading was taken. It reports this information to a cloud based management service along with the date, time and device used to take the measurement. Readings are transmitted to a cloud based management portal through a cellular connection. Analytics track the slipperiness of the floor and alert management when attention is needed or a cleaning has been missed.

The tracking device mounted to the cleaning apparatus can be used to provide evidence of a cleaning regime and real-time feedback via dashboard or text message.

Procedures for dealing with spills can be developed and deployed when the coefficient of friction reading taken by the cleaning apparatus drops below a predetermined value.

Embodiments of a kit for reducing the occurrence of slipping on a floor surface constructed according to principles of the present disclosure can include a tracking device (to monitor cleaning and/or to measure the dynamic coefficient of friction), a plurality of beacons (e.g., three) to indicate location of the cleaning apparatus within the facility, and a floor condition tracking program stored on a non-transitory, tangible computer-readable medium. The kit can be configured to operate via a cellular connection—independent of the Wi-Fi network at the facility. This makes it faster and easier to deploy without the need for onsite visits. The kit can be drop shipped.

In embodiments, the tracking device can be attached to the cleaning apparatus that is already located onsite at the facility as a retrofit. In embodiments, the beacons comprise wireless (Bluetooth) beacons that are “stick-on” adhesive layer for ready attachment to a wall in the facility and do not require any wiring.

In embodiments, the computing system includes a mobile app that is adapted to allow management to query a cloud-based console and to obtain alerts. The mobile app can be configured to perform tracing functions and to provide motivating messages for regularly cleaning the facility according to the determined cleaning schedule.

Parameters can be defined when cleanings have to be performed and where they should be performed within the facility. The cloud based management console makes sure those readings are received at the correct time. If a reading is not received, an alert can be sent by email or SMS to the store manager. In embodiments, an alert is are sent to management if the floor conditions require attention.

The computing environment is adapted to preserve records in a data storage device for later use, such as for management reports. In embodiments, the computing environment is adapted to allow for management reporting over multiple stores in different locations.

The stored data can be imported into spreadsheets or other programs. Real time data reporting and alerts can be collected and displayed in a useful format, data feeds can be made available. Customizations can be made to provide roll up reporting of facility data.

In embodiments of a method of monitoring the cleaning conditions of a facility following principles of the present disclosure, a facility subscribes to a slip reduction service and receives a kit with the components to monitor and report both the cleaning operations occurring at the facility and the measurements of how slippery the floor is. This information is transmitted via a cellular connection to a cloud based service. Details of reading from the store are kept in the cloud for management. This information is used to generate alerts when cleaning operations have not been performed according to a predetermined schedule and/or if the floor condition should be checked due to a low coefficient of friction reading. It can also be used to respond to claims and monitor the overall cleanliness of stores.
